Application filed March -1, 1922. Serial No. 540,256.

T 0 all whom it may concern Be it known that I, NORMAN W. NU'r'r, acitizen of the United States, residin at Trenton, in. the county ofMercer and tate of New Jersey, have invented certain new;

and useful Improvements in Electric-Lamp Fixtures or Supports, of whichthe following is a specification.

This invention relates to certain improvements in electric lamp fixturesor supports generally, and more particularly to combined types of lampsocket husks and shades or reflectors, or globe, shade or reflectorholders.

The principal object of the invention is to provide for devices of theclass mentioned, and of a construction and arrangement tending towardsimplicity in design, ease in assembling and installing, andcomparatively low cost in manufacture.

Another object of the invention is to provide for a means whereby toefiectively ventilate the interiors of electric lamp shades, reflectors,or the holders thereof, or the combined types of shade or reflector andlamp socket holders, whereby the intensive heat, generated by anelectric lamp confined within a shade or reflector, is radiated orotherwise allowed to escape therefrom.

WVith the foregoing and other equally important advantages and objectsin view, the invention resides in the certain new, novel and usefulconstruction and arrangement of parts as will be hereinafter more fullydescribed, set forth in the appended claim, and illustrated in theaccompanying drawing which illustrates in side elevation, partly insection, a combined electric lamp socket and shade holder in accordancewith this invention, the parts of the same being shown in position forthe assembling thereof,

Referring to the drawing, and the numeral 10 indicates generally theupper portion of an electric lamp socket inclosing husk, which is closedat its upper end by a curved or semi-spherical wall portion 11, and isopen at its lower end for the impression into position therein of a lampsocket (not shown). The lower open end of this portion of the husk 10 isscrew-threaded, as at 12, for the attachment thereto of the lowerportion 13 of the husk, which is intogrally formed at the upper end of asubstantially conical shaped shade or reflector body 14, the portion 13thereof being screwthreaded complementally to the threaded portion 12,of the husk body, for the purpose. Medially between .the integrallyformed threaded husk portionc' l3 and-the upper 'end of the. shadereflector proper, there is providedan annular or substantially.cylindrical wall portion 15, which is formed with a series ofequidistantl'y spaced open-' ings 16, whereby to ventilate the interiorof the shade or reflector and to greatly reduce the temperatureimmediately around the base of the lamp bulb (not shown) positionedwithin the shade or reflector, and the lamp globe supporting socket (notshown)- housed within the husk portions 10 and 13.

In the use of this type of light support or I fixture, the upper huskportion lO'has its end wall 11 formed with a centrally arranged opening,as at 17 through which the free ends ofa pair of circuit conductors (notshown) are threaded for'attachment to the binding contacts or screws ora lampsocket inserted upwardly of the lower open end therof, when thelower husk portion 13 and the shade or reflector 14, will be threadedonto the lower threaded end 12 of the 1 either insulating ornon-insulating, capable of being pressed or moulded into the requiredconfiguration or form.

From the foregoing it will be readily apparent to the electrical trade,that-the invention provides for novel, useful and attractive form ofelectric lamp support or fixture, providing a combined lamp socket andshade and reflector husk and holder of simple and inexpensiveconstruction and arrangement, affording quick and easy assembling andinstalling of the same and the associated parts thereof with a markedreduction in the manual operations required for the purpose, and in timefor the accomplishment thereof, and, by, the provision of the means forventilating the interiors of the parts of the fixture or support, thehandling of the same is facilitated when in use, without the usualannoyance and discomfort occasioned by the heating up of the parts bythe lamps positioned within the globes, shades or reflectors.

It is well understood that, while the preferred embodiment of theelectric lamp fixture or support have been described and illustratedherein in specific terms and details of construction and arrangement,various changes in and modifications of the same may be resorted towithout departing from the spirit of the invention, or the scope of theclaim appending hereto.

Having thus fully described the invention, what is claimed, is

An electric lamp husk comprising a hollow upper section cylindricalthroughout and having a top portion formed with a central opening, thelower terminal portion of said section being threaded internally andexternally and with the threads thereof terminating at the lower edge ofsaid section, a lower section including a cylindrical upper portion anda flaring lower portion, said upper portion having its upper partthreaded internally and externally for engagement with the threads ofthe upper section and further for engagement with the threads of a lampsocket and said upper portion having the lower part thereof formed witha series of openings spaced from said flaring portion of said lowersection.

In testimony whereof, I afiix my signature hereto.

NORMAN W. NUTT.
